Temperature compensation for high-birefringence fiber loop mirror

SPIE Proceedings, 2005
We propose a novel temperature compensation method that HBF is mounted on a piece of organic glass. It can lessen its temperature sensitivity to 0.059 nm/K, which are two orders of magnitude lower than that of an uncompensated HBF loop mirror. It is feasible that HBF loop mirror packaged with a large thermal-expansion material is insensitive to ambient

Chromatic dispersion monitoring technique using birefringent fiber loop

2006 Optical Fiber Communication Conference and the National Fiber Optic Engineers Conference, 2006
A chromatic dispersion monitoring technique using birefringent fiber loop is proposed. An unambiguous measurement range of 1500-ps/nm for 10-Gb/s NRZ signal is demonstrated without transmitter modification. This technique can be used to monitor multiple channels.

Nonlinear optical fiber loop mirror with feedback using high birefringence fiber in the loop

Nonlinear Guided Waves and Their Applications, 2004
The dynamics of a nonlinear optical fiber loop mirror with feedback using CW input and high birefringence fiber is examined. Results show dynamical behavior of the device can be controlled with different input polarization angles.

Multiwavelength fiber laser based on a high-birefringence fiber loop mirror

Laser Physics Letters, 2006
In this letter, we propose a novel multiwavelength fiber laser based on fiber loop mirror formed by a high-birefringence fiber, a polarisation controller, and a 3 dB directional coupler. By setting the polarisation controller as half-wave-plate, the fiber loop mirror acts as a polarisation-independent wavelength filter; Erbium-doped fiber (EDF ...

Nonlinear optical loop mirror with low birefringence twisted fiber in the loop

Optics Communications, 1998
Abstract The fiber loop mirror constructed from low-birefringence twisted fiber was numerically examined. Nonlinear ellipse rotation effect has been taken into account. Nonlinear switching has been found for the balanced configuration with a 0.5/0.5 coupler.

A hydrophone based on high-birefringence fiber loop mirror

SPIE Proceedings, 2010
A new type of hydrophone based on high-birefringence fiber loop mirror (HiBi-FLM) is proposed and demonstrated. The sensing part is a section of high-birefringence fiber wound onto a hollow metal cylinder fiber. A narrow band light source is used and the detection is done by measurement of light intensity.

Multiwavelength erbium-doped fiber laser with a high-birefringence fiber loop mirror

Conference on Lasers and Electro-Optics (CLEO 2000). Technical Digest. Postconference Edition. TOPS Vol.39 (IEEE Cat. No.00CH37088), 2000
Summary form only given. With the rapid development of wavelength-division-multiplexed systems in optical communication, multiwavelength laser sources have attracted considerable interest. Several types of multiwavelength rare-earth-doped fiber lasers have been demonstrated, which differ in the wavelength-selection methods used.

A fiber Bragg grating demodulation system using high-birefringence fiber loop mirror

SPIE Proceedings, 2014
In this paper, a fiber Bragg grating (FBG) demodulation system based on high-birefringence fiber loop mirror (Hi-Bi FLM) is proposed and demonstrated. The approximate linear edge of the transmittance of the Hi-Bi FLM, which is a sinusoidal function of wavelength, is used to interrogate the sensing FBGs. The relationship between the wavelength period of

Fiber optic sensors based on birefringence fiber loop interferometer

17th Congress of the International Commission for Optics: Optics for Science and New Technology, 1996
A high-birefringence polarimetric fiber sensor [1] typically includes a single mode polarization preserving fiber, an output polarizer and a detector. Two independent orthogonally polarized modes are propagating within the fiber and their phase difference may depend on pressure, temperature or other external parameters.

A novel high-birefringence fiber loop mirror electric current sensor

SPIE Proceedings, 2007
A novel electric current sensor based on a high-birefringence fiber loop mirror(HBFLM) and a kind of magnetostrictive material rod(MMR) is demonstrated theoretically and experimentally. Part of the high-birefringence fiber(HBF) is pasted onto the MMR which is placed in the central part of a solenoid.
